This invention relates to loom harness, and it relates more particularly to improved means, in

.a heddle frame, for securing the ends of the rods upon which the heddles are mounted.

Heretofore, various forms of devices have been used for the purpose of securing the rods upon which the heddles are mounted in loom harness The most satisfactory forms of such devices were those which were mounted on the outer faces of the end struts of the frame.

However, while it has long been recognized that it is advisable, principally for safety as well as for other purposes, to keep the outer faces of the end struts of the frames free from projections and devices which tend to catch the hands of the weavers as well as becoming fouled on other objects, it has been found difficult to provide a satisfactory securing device on the inside of the end strut-s of the frame.

. The principal object of the present invention I is to provide, in a loom harness heddle frame,

improved means for securing the ends of the 4 Claims. (Cl. 13992) changes may be made in thc'structure'disclosed without departing from the spirit of the invenheddle rods, which means are disposed entirely within the interior of the frame.

A further object of the present invention is to provide a device of the character aforesaid which may be pivotally mounted so that the same may be swung outward to disengage it from the end of the heddle rod. I

A further object of the present invention is to provide a device of the character aforesaid with novel locking means which will efiectively prevent the accidental disengagement of the securing device from the end of the heddle rod. The nature and characteristic features of. the invention will be more readily understood from the following description, taken in connection with the accompanying drawing forming part hereof, in which:

Figure 1 is a front elevation of a loom harness heddle frame provided with heddle rod securing devices embodying the main features ,of the present invention;

Fig. 2 is an enlarged section thereof taken on the line 22 of Fig. 1;"

Fig. 3 is a perspective view of one corner-portion of the heddle frame, illustrating more particularly the device of the present invention in its relationship with other parts of the frame;

and

Fig. 4 is aperspective view of the securing device of the invention detached from the frame. It should, of course, be understood that the v for the securing of ,various types of example, the "rails l0 connected by end tion.

Referring to' the 'drawing,' the heddle frame proper'may be of any preferred construction, for s'ame'may comprise top andbottom struts II. The end struts Il may be of a composite character consisting of centralwooden strips [2, having metallic strips l3 and I4, respectively; mountedon the inner and outer faces of said wooden-:strips- I2. The ends of the metallic strips -I 3 and I4 are'bent over and secured to the inner and outer edges, respectively, ofthe top "and bottom rails In in the usual manner. D

The heddle supporting rods I5 may be of any preferred type, comprising strips of fiat metal which extend from end to end of the frame. The

ends of the heddle'suppo'rting rods l 5"are-normally seated in slots '16 extending through'the end-struts I l. The heddle supporting rods- [5' are preferably of-such length so as not-to project beyond the outer faces of the metallic strips-J4 oftheendstrutslL- The heddles 36 are mounted on the heddle rods l5 in any preferred manner as it will be apparent that the device of the present-invention-is applicable to various types of harness frames, and heddle rods in such frames.

Each of the heddla-rofdsl5' is provided near each end with an'aperture I] adapted to be engaged by a portion of the securing. device as will be hereinafter more fully set forth.

, The securing device offthe present invention of *thin' fiat spring metal is preferably -made I punched and formed to provide the several 'component parts thereof. The same is secured to the inner face of the metallic'strip' [3 of the end strut H by means of ,a rivet l8, upon which it is pivotally mounted. Thendevice has'..anl'arm l9 extending from thepivotaliportion and is' cut away onone side to 1 provide a recess' 2 li into which a prong 2-! projects. The arm portion l9 also has an extension 22 beyond/the prongv 2| whichis curved at the :free end to facilitate manual engagementthereoffor the purposeof manipulation. i The aperture l'l near theend of the heddle rod I5 is engaged by the prong 2| when the securing device is in its normal operative position, and the tension of ,the arm l9 will not only serve to stress the heddle rod to hold the same taut, but will also serve to maintain the end of the heddle rod in the recess or slot IS in which it is normally seated.

Oppositely disposed with respect to the main arm IQ of the securing device is another arm 23 having an inwardly extending lug 24 formed on the end thereof by bending the same. This lug 24 normally engages an aperture 25 in the strip l3 of the end strut I I.

When the securing device-is in its normal operative position the arm I9 is stressed to maintain the heddle rod l 5 taut and, also, to maintain the end of the heddle rod l5 within its slot Hi.

When it is desired to disconnect one end of a heddle rod for the purpose -of-removing or=adding heddles, the arm I9 "at-that'location'will be swung sidewise on its pivotwhioh-will cause' the lug 24 at the free end of,.the-arm %23--to be disengaged from the aperture 25 in the metallic strip [3, whereupon the prong 2| may be disengaged from the aperture I! in the end portion Df the'heddl'ezrod.

When the tsecuringxdevice atone- 'endrofaiheddle rod is thus disengaged therefrom the similar idevicei at the .othervend of the said rod 'will, by

"reason .ofithe normal :stress thereofpmovethe ihe'ddle zrodylengthwisea sufficient distanceto iipermit the endthereof tobeifreed from the slot '16 so::that additional heddles may be mounted mn-"the :heddle rodtat that-end,orif-desiredsome ibflth heddles may-be thus removed.
